veryyoudaoicibaDictYouDict[very 词源字典]
very: [13] Latin vērus meant ‘true’ (it came ultimately from Indo-European *wēros, source also of German wahr ‘true’, and it has also given English verdict, verify [14], verisimilitude [17], and veritable [15]). From it was derived Vulgar Latin *vērāius, which passed into English via Old French verai. Very was originally exclusively an adjective, meaning ‘true’. It was not used as an adverb, meaning ‘truly’, until the 14th century, and its modern role as an intensifier did not begin to emerge until the 15th century.
